The retention behavior in supercritical fluid chromatography (SFC) remains a complex and poorly understood phenomenon despite the development of various models to explain retention mechanisms. This study aims to deepen the understanding of retention by investigating three distinct stationary phases: high-strength silica octadecyl (HSS C18 SB), charged surface hybrid pentafluorophenyl (CSH PFP), and porous graphitic carbon (PGC) as a nonsilica-based phase. Three mobile phase compositions, i.

Background Human epidermal growth factor receptor 2 (HER2)-positive breast cancer is a highly aggressive subtype characterized by a high recurrence rate. Trastuzumab emtansine (T-DM1), an antibody-drug conjugate targeting HER2, has shown improved outcomes; however, its effectiveness in cases with brain metastases remains unclear. The T-DM1 biosimilar has emerged as a cost-effective treatment option.

Within the context of the circular economy, the transformation of agri-food waste or by-products into valuable products is essential to promoting a transition towards more sustainable and efficient utilisation of resources. Whey is a very abundant by-product of dairy manufacturing. Apart from partial reutilisation in animal feed or some food supplements, the sustainable management and disposal of whey still represent significant environmental challenges.

Inspired from heat shock proteins (HSPs), a thermo-sensitive coacervate-forming polycaprolactone (CPCL) was designed as a natural chaperone mimic to protect proteins from thermal stress. Unlike the coil-globule polymers of poly(-isopropyl acrylamide) (PNIPAM), the as-designed CPCL underwent a partial dehydration during heating, characterizing it as a coacervate-forming polymer. With its ability to transform between the coil and coacervate states in response to temperature, theCPCL spontaneously captured and released targeted proteins, thereby behaving like a natural chaperone of HSPs.

Objectives: Well-differentiated neuroendocrine tumors (NET) are highly vascular tumors characterized by their expression of vascular endothelial growth factor (VEGF). This trial investigated the activity of ramucirumab, a monoclonal antibody that targets VEGF receptor-2 (VEGFR-2) and inhibits activity of VEGF, in combination with somatostatin analog therapy in patients (pts) with advanced extra-pancreatic NET.
Methods: We conducted a single-arm phase II trial enrolling pts with advanced, progressive extra-pancreatic NET.
